Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15 TON: Timer1 On bit
1 = Starts 16-bit Timer1
0 = Stops 16-bit Timer1
bit 14 Unimplemented: Read as ‘0’
bit 13 TSIDL: Timer1 Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
bit 12-10 Unimplemented: Read as ‘0’
bit 9-8 T1ECS <1:0>: Timer1 Extended Clock Select bits
(1)
11 = Reserved; do not use
10 = Timer1 uses the LPRC as the clock source
01 = Timer1 uses the external clock from T1CK
00 = Timer1 uses the Secondary Oscillator (SOSC) as the clock source
bit 7 Unimplemented: Read as ‘0’
bit 6 TGATE: Timer1 Gated Time Accumulation Enable bit
When TCS =
1:
This bit is ignored.
When TCS = 0:
1 = Gated time accumulation is enabled
0 = Gated time accumulation is disabled
bit 5-4 TCKPS<1:0>: Timer1 Input Clock Prescale Select bits
11 = 1:256
10 = 1:64
01 = 1:8
00 = 1:1
bit 3 Unimplemented: Read as ‘0’
bit 2 TSYNC: Timer1 External Clock Input Synchronization Select bit
When TCS =
1:
1 = Synchronizes external clock input
0 = Does not synchronize external clock input
When TCS =
0:
This bit is ignored.
bit 1 TCS: Timer1 Clock Source Select bit
1 = Timer1 clock source is selected by T1ECS<1:0>
0 = Internal clock (F
OSC/2)
bit 0 Unimplemented: Read as ‘0’
Note 1: The T1ECSx bits are valid only when TCS = 1.
